No longer a lab exercise, VoLTE is now being aggressively rolled out
into live network trials with mass deployment expected within the year.

Fueled by the explosive growth of LTE data traffic, the need to reduce
operating costs and the promise of new competitive services, VoLTE
presents significant challenges for MNOs to both achieve their business
objectives as well as meet the reliability and quality expectations of
their existing 2G/3G circuit-switch voice subscribers.

"By expanding the BrixWorx service assurance platform with VoLTE/IMS
monitoring and troubleshooting functionalities such as live VoLTE
traffic generation, MNOs can now measure and analyze LTE voice KPIs in
real time, detect potential service degradations and make the necessary
corrections before they impact customers," said Claudio Mazzuca,
Vice-President of EXFO's Transport and Service Assurance Division.
